Feeling hopeful (Life is unpredictable)

I went to the doctor after years of not going. I got blood tested and I have a B12 deficiency and iron deficiency. It was giving me symptoms like fatigue, depression, anxiety, memory loss, difficulty focusing, suicidal thoughts. I’ll find out in a month or two if it fixes me. I was going to kill myself. I don’t even have one friend, I have never had a girlfriend, I don’t have a job. I just have hope, and hope is everything.
